We have been given the values, it is 0 .8 that is 62 .4 multiplying it by 8, we get 42 .92 lb per 5th cube and we have d1 value, d2 value and d3 value.
00:20
It is in inches, it is 5 inch, it is 4 inch and we have this is in 3 inches.
00:28
Similarly, we have p1, it is 25 psig and we have p3 value that is 20 psig.
00:42
We have to find the p3 value for our answer.
00:47
So velocity, velocity it is given by v1 is equal to q1 over a1 and we have q1 value as 10 and e is given by a pi over 4, 5 over 12 whole square since it is pi r square.
01:06
So we have 73 .34 ft per second as the velocity and using the bernoulli from 1 to 3, we can say p1 over this gamma value plus z1 plus v2 whole square over 2g is equal to p3 over gamma plus z3 plus v3 square over 2g.
02:03
Now we can put our values in this to get the value for this v3 and we have 25 over 49 .2 plus 0 that is the z1 value and we have 73 .34 square divided by 2 into 32 .2 which is equal to 20 over 49 .92...
